Supersprox-Stealth rear sprocket

Description

This is a genuine KTM PowerParts item supplied by the motorcycle manufacturer, not an aftermarket replacement. Rear sprocket with high-strength steel teeth for extra long service life and an aluminium centre section that reduces unsprung mass. Permanently joined together with high-strength rivets. Offers at least three times longer service life than other aluminium rear sprockets and is 50% lighter than steel sprockets, extending the service life of the entire drivetrain.
